  address information across an exec, making it possible to by pass ASLR
  (Address Space Layout Randomization). A local user could use this flaw to
  by pass ASLR to reliably deliver an exploit payload that would otherwise be
  stopped (by ASLR). (CVE-2013-0914)

  A memory use after free error was discover in the Linux kernel's tmpfs
  filesystem. A local user could exploit this flaw to gain privileges or
  cause a denial of service (system crash). (CVE-2013-1767)

  Mateusz Guzik discovered a race in the Linux kernel's keyring. A local user
  could exploit this flaw to cause a denial of service (system crash).

  Mathias Krause discovered a memory leak in the Linux kernel's crypto report
  API. A local user with CAP_NET_ADMIN could exploit this leak to examine
  some of the kernel's stack memory. (CVE-2013-2546)

  Mathias Krause discovered a memory leak in the Linux kernel's crypto report
